'THERMOSTATIC LAMP REGULATOR.

Application filed February'IG; 1926... Serial No. 88,645.

My present'invention pertains to lamps used for heating chicken brooders audit; has for its object the provision of peculiar' and advantageous thermostatic lamp regulatingv means; the said means serving to maintain a predetermineddegree' of heat afforded by the lamp and also serving incidentally to save oil.

Other objects and practical advantages of the invention will be fully understood from the following description and claim when the same are read in connection with the drawings, accompanying and forming part of this specification, in which Figure 1 is a view partly in elevation and partly in section, showing one embodiment of my invention in association with parts of a brooder.

Figure 2 is a top plan view of the same.

Figure 3 is an enlarged fragmentary view illustrative of the connection between the levers comprised in my improvement.

Figure 4 is a fragmentary section on an enlarged scale showing the connection of the lower lever to the rotary member through which the wick of the lamp is raised or lowered.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

I illustrate in Figures 1 and 2 an oil reservoir 1, and I also illustrate a conventional lamp 2 connected through a conduit 3 with the reservoir 1. The wick of the lamp 2 is raised and lowered through the medium of a rotary or turnable element 4 having an enlargement 5 at its outer end, the wick being raised incident to turning of the element 4 in one direction and lowered on the turning of the element 4 in the opposite direction. In furtherance of my invention a lever 6 is fixedly connected to the element 4 for the turning of the said element 4 in one direction or the other as conditions require. The said lever 6 is provided with apertures 7 for adjustment purposes and terminates at one end in an enlargement 8, connected through the medium of bolts 9 and nuts 10 or other appropriate means with the enlargement 5. A conventional drum 11 is shown in Figures 1 and 2, as having one of its ends connected with and adapted to receive heat and other products of combustion from the lamp 2, the opposite end of the said drum 11 being adapted to be connected at 12 with an uptake, not illustrated.

superposed upon a support 13 and ar rangedbettveenthe parallel portions of the drum 11 is a thermostat 14 which may be and preferably is of the ordinary well known expanding and contracting type. above and in spaced relation to the thermostat 14 is a "ertically swingable lever 15, pivoted at 16 to an appropriate support interposed between the parallel portions of the drum 11 and adjacent to the bight of the drum. At 17 the lever is provided with a screw which is threaded in the lever 15 and bears upon the upper side of the thermostat 14. The screw 17 serves for adjustment purposes, it being understood in this connection that expansion of the thermostat 14 will be attended by raising of the lever 16, while contraction of the thermostat will bring about downward movement of the lever 15. Connected with and pendent from the free portion of the lever 15 is a U-shaped bail 18, and extending loosely through an aperture in the lower cross portion of the said bail 18 is a threaded rod 19*, equipped above and below the said cross portion with nuts 19. These nuts 19 serve to adjustably fix the rod 19 to the bail 18, and manifestly when the said nuts are loosened the rod 19 may be raised or lowered as conditions require. The rod 19* is connected to the apertured lever 7, and by shifting the rod 19" relative to the lever 7, the throw of the lever under the action of the thermostat 14 may be regulated.

In the practical operation of my improvement it will be manifest that when a certain predetermined degree of heat is present in the drum 11 and the thermostat 14 is expanded to a predetermined extent, the rotary element 4 will be turned to lower the wick of the lamp 2, and then when the diminution of the heat in the drum 11 brings about contraction of the thermostat 14, the element 4 will be turned to raise the wick. By virtue of this automatic operation the consumption of an unnecessary quantity of oil will be averted and at the same time the drum 11 will be maintained at a certain predetermined degree of heat as is highly de sirable in chicken brooders and the like.

It will be apparent from the foregoing that my novel organized mechanism is simple and inexpensive in construction, is susceptible of ready installation, and is reliable for attaining the ends stated.

have entered into a detailed description of the construction and relative arrangement Arranged standing of the sa dembodhnenth Idonot (leesire, however, to lie understood as limiting myself to the. preczse construction and-:relw

tire arrangement of parts as disclosed, my invention being? defined by myappended claim within the scope of which changes in structure anal in arrangement maybe made without departure from myinvention.

Having described my invention, what I claim and desire to secure by Letters'Patent; is:

Ana adjustableconnectoradapted to be interposed between a thermostatically controlled lever and a lamp controllin lever commising ee UJSha I LhaEI having a bight portion, a rod Slidehle through the opening, andupnutrthmadeel on the rod to engage the bight portion so that the rod may be ad insect-in relhtion'tdth'e hail, eaid hail adapt ed to be connected with one lever and said rofi'adaptedxtobe connected to theoth'er lever.
